Title: Interactive image matting using neural networks
Inventor: BRIAN LYNN PRICE
IPC: G06T7/194
Filed: 2019-12-19
Abstract: A method for using a deep neural network (DNN) to perform image matting comprises receiving an input image 110 and user input 105 specifying a foreground location in the image, generation of a binary mask 130 based on the user-specified foreground location, generation of a trimap 150 based on the user-specified foreground location and the binary mask, and generation of an alpha matte 170 based on the trimap and the user-specified foreground location. The generation of the binary mask, trimap, and alpha matte are performed by the DNN 120, 140, 160. The training of the DNN may minimise a loss function based on a comparison of the generated alpha matte pixels for a training image and ground-truth alpha matte pixels associated with the image. The method may comprise down-sampling the input image to produce a second image and the production of a first alpha matte based on the original image and a second alpha matte based on the second image. The DNN may generate a foreground and/or background colour decontamination map providing colour channels associated with the alpha matte. A computer program for the production of trimaps using input images, binary masks, and user inputs is also disclosed.

Title: Image pickup apparatus having a plurality of settable image capturing modes
Inventor: TAKUO TSUCHIYA
IPC: H04N5/235
Filed: 2019-06-26
Abstract: Image pickup apparatus including an image sensor and having capturing modes providing methods for controlling exposure control values (e.g. shutter speed (302), aperture value (303), ISO sensitivity (304)) is controlled to change exposure when capturing a subject image. Mode (301) transitions are controlled by a user manually operating a first operation member, and individual exposure control value changes are separately controlled by manually operating a second operation member. First, second, and third modes are provided. The first (semi-automatic) involves an exposure control value being set to a fixed value by the user, and other exposure control values being set to settable automatic values by the apparatus without involving the user. The second (fully automatic) involves the exposure control values all being set automatically (e.g. displayed as underlined). The third involves the exposure control values being settable to a combination of the automatic value and the fixed value settable in the first and second modes by the user via the second operation member, without changing the image capturing mode. Image capturing modes are therefore available where exposure control values can be changed simply without a sense of discomfort due to capturing mode changes. Auto bracketing and HDR functions are disclosed.
